CIRCUIT-CLOSING RELAY.

Sueciiieation of Letters Patent.

Application filed May 12, 1908. Serial No. 482,336.

T all whom it concern:

Beit known that I, JEAN F. WEBB, J12, residingat Denver, in the county of Denver and State of Colorado, have invented certain new and. useful Improvements in Circuit-Olosing Relays, of which the following having a contact device to close a. local circuit, and meaiis for iocking the armature in its circuit closing position, together with "means whereby the armature may be rcieased from its locking position at timesa In its more suborchnate nature the invention ,embodies those novel details of conparts, which will be first fully described, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Figure 1, is aperspective View of my improved form of relay removed from the casmg. Fig. 2, is a front elevation thereof, the

parts being in the casing. Fig. 3, is a central vertical longitudinal v sectionwn line 3 3 of Fig. 2, Fig. it, is a detail View illustra-ting a slight modification of my invention. Referring now to the accompanying drawings, in which like letters and numerals of reference indicate like parts in all of the figures, .1 designates thecasing which has a removable door or closure member l and within the casing 1 the insulating support- 2' is mounted in any approved manner. To the support 2 a frame 8, which supports the yoke i of the electro-magnet 5 is secured.

v 46 The frame 3 The yoke iis insulated from the frame 3, as and 3 of the drawings. comprises the horizontal por tion '3 that supports the yoke i, the vertical front portion 3, and the bottom horizontal portion 3 that terminates in the front U- shaped member 3, that provided with hearing apertures iorthc shafts 9 and i0.

hereinafter again referred to.

(i designates an armature supporting: frame having lugs (3 to receive the bee-r ng .screws (3 that support the armature 7, the armature 7 carrying a contact spring 7*, so as to contact with the frame 3 when the armature is lifted by the magnets 5 and close the electric circuit between the frames 3 and 6, to which the terminals of the local circuit 13 is connected, the circuit 13 including a source of electric energy 15,'and a signal 14, of any, approved type.

The armature 7 is provided with proiecting portion 7 thatis adapted to engage the seats 8* and 8 of an insulated stepped block 8 that is carried by the shaft 9 to move therewith.

The shaft 9 is geared by means of gears 9 i0 With shaft 10 to which the lever 11 is secured in such a manner that its weight rotates the shafts 10-9 when the armature f 7 comes into alinement with the step 8, so that the step 5 will hoid the armature in its circuit closing position. The lever 11 is also adapted to be engaged, and when its movement is in a direction opposite to that just describf d, it will rotate t-he'shafts 10--9 I correspondingly and thereby move the step 8 out of engagement with the armature portion 7* and permit the armature to gravitate to its circuit opening position.

In order to complete the" electric circuit fully between the armature 7 and the frame 6, an electrical connection '1 is provided. This insures a good contact between the armature and its supporting frame at all times. r p The contact spring 7 that is carried by the armature 7, to "enga ge the frame 3 when the armature is drawn up by the magnets 5, also aids in forcing the armature away from the frame 3 to openthe circuit when the magnets '5 are dciinergizcd and the step 8 is moved out of engagement;

lnsteadof mounting the lever 11. on the shaft 10 and turnin the block 8 through the gears 9 and it), i may mount the lever 11 directly on the shaft 9 so that a direct movement oi the lover will suiiice to move the biock 8 to release the armature, (see Fig. i-

The magnets 5 are adapted to be connected in the main linecircuit 1 which includes any approved type of circuit closer l9 and any approved source of electric magnets supported thereby, a second sup and adapted to engage the magnet support- The uses to which my invention can be applied are numerous, and it is not thought necessary to state them here as they will be readily apparent to those skilled in the art to which the invention appertains.

From the foregoing description taken in connection with do accompanying drawings, it is thought the complete construction, operation and advantages of my invention will .be readily understood by those skilled in the art to which the invention appertains, and I desire to say that slight changes in the details of construction may be made without departing from the spirit of the invention or the scope of the appended claims.
